SB2018123001 - OpenSUSE Linux update for libraw

Description

This security bulletin contains information about 5 vulnerabilities.

1) Type confusion (CVE-ID: CVE-2018-5804)

CWE-ID: CWE-369 - Divide By Zero

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear

The vulnerability allows a local attacker to cause DoS condition on the target system.

The vulnerability exists due to type confusion error within the "identify()" function (internal/dcraw_common.cpp). A local attacker can supply a specially crafted input, trigger divide by zero error and cause the service to crash.

2) Stack-based buffer overflow (CVE-ID: CVE-2018-5805)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear

The vulnerability allows a local attacker to cause DoS condition on the target system.

The weakness exists due to stack-based buffer overflow within the "quicktake_100_load_raw()" function (internal/dcraw_common.cpp). A local attacker can submit specially crafted images, trigger memory corruption and cause the service to crash.

3) NULL pointer dereference (CVE-ID: CVE-2018-5806)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear

The vulnerability allows a local attacker to cause DoS condition on the target system.

The weakness exists due to an error within the "leaf_hdr_load_raw()" function (internal/dcraw_common.cpp).  A local attacker can submit specially crafted images, trigger NULL pointer dereference and cause the service to crash.

4) Stack-based buffer overflow (CVE-ID: CVE-2018-5808)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the find_green() function, as defined in the internal/dcraw_common.cpp source code file in LibRaw versions prior to 0.18.9. A remote attacker can trick the victim into processing a specially crafted input, trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

5) Infinite loop (CVE-ID: CVE-2018-5816)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to a divide by zero integer overflow condition in the identify() function, as defined in the internal/dcraw_common.cpp source code file in LibRaw versions prior to 0.18.12. A remote attacker can trick the victim into processing a specially crafted NOKIARAW file, trigger an infinite loop condition and cause the service to crash.
